Answer 6

2nd to last question. :)

Answer 7

@dpaInc @Callisto Thoughts?

Answer 8

C, I think?!
right -> with angle =90 degree
From the diagram, we see AB is perpendicular to XY -> 90 degree
So, keep R at its position, move Q to the line AB (upward or downward, doesn't matter)
To have isos triangle, the length of 2 sides must be equal for the radii of a circle, they must be equal!!

So, probably, it's C
